Curated dataset of multinary alloy HER catalysts for composition-only modelling with Magpie descriptors and GP baselines.
High-entropy alloy (HEA) electrocatalysts offer a large design space for the hydrogen evolution reaction (HER), but literature data are sparse, heterogeneous and often difficult to reuse for quantitative modelling. Here we present a curated dataset of 180 multinary alloy catalysts compiled from published sources, with...
